Device and method for automatically braking and stopping during freight train derailing

Abstract

The invention discloses device and method for automatically braking and stopping during freight train derailing. The device comprises a vibrating sensor module, a vibrating spectrum analyzing and processing unit, an automatic charging and energy storing device, an electromagnetic valve, a braking device and a storage module. The method comprises the following steps of: adopting a digital sensor to pick up vibrating signals of wheel pairs and bearings of a train; picking up vibrating information of characteristic frequency bands through a frequency domain analysis method; judging whether the running of the train derails or not and storing vibrating characteristic data into a nonvolatile memory for state recording; and if the train derails, starting an alarm mechanism, acting by the brake device to brake the train until stopping, and sending an alarm signal by an audible and visual alarm device. The invention is used for monitoring the running state of a rail wagon in real time and can detect faults and hidden dangers and send out early warning signals for states being possible of derailing for preventing accidents.

Description

technical field [0001] The invention designs a derailment automatic braking and parking device and method for freight trains, and belongs to the technical field of dynamic testing and calibration of derailment automatic parking. Background technique [0002] During the operation of freight trains, accidents of wheel derailment occur frequently due to various reasons. Because there is no effective way to detect and brake urgently in time for the derailment of freight cars, it causes great losses and troubles to the railway engineering department every year, and affects the normal transportation of the railway to a large extent. [0003] In addition to causing harm to the safety of the truck itself, the derailment accident of the truck will also cause accidents such as cutting sleepers to cause damage to the line and cause danger to other vehicles running at high speed on the line. Especially in the case of the current railway speed-up and the implementation of EMU operation,...

AI Technical Summary

Problems solved by technology

As there is currently no effective way to detect and brake the derailed trucks in time, it has caused great losses and troubles to the railway engineering department every year, and has greatly affected the normal transportation of the railways.

[0003] The derailment accident of the truck will not only cause harm to the safety of the truck itself, but also cause accidents such as cutting sleepers to cause damage to the line and cause danger to other vehicles running at high speed on the line

Especially in the case of the current railway speed-up and the implementation of high-speed train operation, the derailment accident of freight trains may cause major property and personnel damage and loss in the current railway operation process, with serious consequences
